No. If two parents both have A blood then they are either AA or Ai. This means they can have a child with AA, Ai, or ii (O blood). To get AB there must be a B somewhere.

Can parents that are both a negative have an ab positive child?

No. If both parents are A negative the child can only be A negative or O negative. If the child is AB positive at least one parent must have type B or AB blood and at least one must be RH positive.


Can parents both blood type b positive have a child with blood type ab positive?

Yes, it is possible for two parents with blood type B positive to have a child with blood type AB positive. This is because the child can inherit one B allele from each parent to make blood type AB.


Can parents with both negative blood parent a positive child?

absolutely. as long as one of the parents is positive, the child can be positive. and if one parent is A the other B, the child can be A, B, AB or O depending on the parents' other alleles. so the child can definitely be A or B positive, but also A negative, B negative, AB negative, AB positive, O positive or O negative.


Father AB positive and mother B positive can child be A negative?

Yes, it is possible for parents who are AB positive and B positive to have a child who is A negative. This is because a child can inherit one A and one Rh negative gene from the parents, resulting in blood type A negative.


Can parents who are b positive have ab positive baby?

Yes, it is possible for parents who are B positive to have an AB positive baby. This would occur if one parent is B positive with the genotype BO and the other parent is AB positive with the genotype AB. The child could inherit the A and B alleles from each parent, resulting in an AB blood type.

No. Nor can someone with AB have a child with O.


Can a mother has A positive blood type and a father has AB positive and the child has B positive?

Since both parents are Rh+, the child will also be Rh+.If the Mother is A0+ and Father is AB+, the child will be: AA+ AB+ AO+ or BO+ So yes this does produce a B+ child.If the Mother is AA+ and the Father is AB+, the child will be AB+ or AA+ neither of these is B+ so this doesn't produce a B+ child.

Of course, you got your blood group from one of your parents or one of your grandparents.
